Table 5: Selected model solutions for the double envelope-ejection scenario. This table is an excerpt of the total list of 122 entries. The first nine columns show the number of the entry, the double white dwarf that the model is a solution for, the prescription used, the two envelope-ejection parameters, the age difference of the two components as observed and in the model ( $\Delta \tau $) in Myr, the relative difference between the observed and model age difference, defined as $\Delta(\Delta\tau) \equiv \left\vert\frac{\Delta\tau_{\rm mod} - \Delta\tau_{\rm obs}}{\Delta\tau_{\rm obs}}\right\vert$ in %, the time of the formation of the double white dwarf since the ZAMS ($\tau _2$) in Gyr. The last nine columns list binary parameters: the initial (ZAMS) masses, mass ratio and orbital period, the intermediate mass ratio and period and the final masses and period.
